Donuts are always selling out at the popular donut shop in town run by the Badger Sisters, who bring them in every day from far over the mountains. It takes far too much work to keep transporting the donuts every morning.Luckily, the Mole Construction Company is the best of the best, and they're eager to help out! The moles get to work tunneling through the mountains, repeatedly boring and hauling out rocks, and are even assisted by armadillo plasterers! Using all sorts of tools and vehicles like a jumbo drill, a hydraulic breaker, and a loader, the moles renovate a shop in town. Everyone rejoices when it reopens and every shelf is chock-full of the Badger sisters' delightful donuts!
